We branching!
I looked at gpu-screen-recorder
Because I have now hw encoder in my RX550 I Aalso tested this program:
it goes up to 52-55 fps for 1440*900 (8bpc) screen.
just a bit shy of 60 fps ;)
May be there is way to speed it up a bit, or live with 30 fps screen recording as before (just with much smaller filesize at expense of some fuzzy color edges)
it sets
AVHWFramesContext *hw_frame_context = (AVHWFramesContext*)frame_context->data;
hw_frame_context->width = video_codec_context->width;
hw_frame_context->height = video_codec_context->height;
hw_frame_context->sw_format = self->params.color_depth == GSR_COLOR_DEPTH_10_BITS ? AV_PIX_FMT_P010LE : AV_PIX_FMT_NV12;
hw_frame_context->format = video_codec_context->pix_fmt;
hw_frame_context->device_ctx = (AVHWDeviceContext*)self->device_ctx->data;
so may be we need to set AV_PIX_FMT_P010LE and not just P010?
